I have a 2019 Outback 3.6R, 53,500 miles, Regular full synthetic oil changes by station. Experienced a sound sound, rough idle and blinking engine light while driving up hill about 30MPH. The knocking sound seems to be coming from drivers side, middle front. I have codes (Current Fault: P0300 & P0304 - Powertrain Pending Fault: P219B- Powertrain). I ordered spark plugs and coils, but I do not think that's the sound? Below is the link of the video. Any thoughts are appreciated. Thanks for reading!
